Luteinizing hormone (LH, also known as luteinising hormone, [1] lutropin and sometimes lutrophin [2]) is a hormone produced by gonadotropic cells in the anterior pituitary gland. The production of LH is regulated by gonadotropin-releasing hormone (GnRH) from the hypothalamus. [ 3 ]
GnRH modulators affect the secretion of the gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which in turn affects the gonads, influencing their function and hence fertility as well as the production of sex steroids, including that of estradiol and progesterone in women and of testosterone in men.
Signs of hyperestrogenism may include heightened levels of one or more of the estrogen sex hormones (usually estradiol and/or estrone), lowered levels of follicle-stimulating hormone and/or luteinizing hormone (due to suppression of the hypothalamic–pituitary–gonadal axis by estrogen), and lowered levels of androgens such as testosterone (generally only relevant to males).

Hypergonadotropic hypogonadism (HH), also known as primary or peripheral/gonadal hypogonadism or primary gonadal failure, is a condition which is characterized by hypogonadism which is due to an impaired response of the gonads to the gonadotropins, follicle-stimulating hormone (FSH) and luteinizing hormone (LH), and in turn a lack of sex steroid production.

Histrelin is also available in a 12-month subcutaneous implant (Vantas) for the palliative treatment of advanced prostate cancer, since 2005 in the US, and since January 2010 in the UK. A 12-month subcutaneous implant (Supprelin LA) for central precocious puberty (CPP) was approved in May 2007, by the US Food and Drug Administration .
Medications used in hormone therapy for transgender men include androgens and anabolic steroids like testosterone (by injection and other routes) to produce masculinization, suppress estrogen and progesterone levels, and prevent/reverse feminization; GnRH agonists and antagonists to suppress estrogen and progesterone levels; progestins like ...
Degarelix, sold under the brand name Firmagon among others, is a hormonal therapy used in the treatment of prostate cancer. [3] [5]Testosterone is a male hormone that promotes growth of many prostate tumours and therefore reducing circulating testosterone to very low levels is often the treatment goal in the management of advanced prostate cancer.
In 2019, 24,123 male patients underwent surgical treatment for gynecomastia in the United States, accounting for a 19% increase since 2000. Thirty-five percent of those patients were between the ages of 20 and 29, and 60% were younger than age 29 at the time of the operation.
